How to connect the circuit diagram of the automobile generator

Check the output wiring of the generator and find B+, F, N, E, which are positive electrode B+ (thickest), excitation end F (thin wire), respectively Sex end N, 3rd end (not wired in this figure), ground E (right side connected to the shell).

The automobile generator has three or four wiring columns. The thickest is the fire wire B, which is directly connected to the positive fire wire of the battery. The thinner one marked with F is the magnetic field connecting column, which is connected to the output end of the regulator. The other one marked with E is the grounding (iron), which can be connected to iron or battery iron wire. The four lines marked with N are neutral points, which can generally be unconnected.

The wiring diagram of the V generator is as follows: B+ is connected to the positive pole of the battery. N neutral point is the one that controls the charging indicator light, which can be connected or not. F is the magnetic field, and the F of the regulator. Grounding, the body is ironed, and the negative pole of the battery can also be connected. Regulator + ignition switch ACC gear. The regulator F is connected to the generator's F.

The wiring on the vehicle generator is also different depending on the model. The most common ones generally have the following wires, B connecting column,It is the thickest and largest junction column on the generator. This wire is the output line of the generator and the positive pole of the battery; other junction columns also have F, N - (some are marked as E).

Toyota series circuit recognition diagram

In Toyota's circuit diagram, the junction box is also called J/B, including cabin junction box, instrument Disc junction boxes and other junction boxes.The internal circuit diagram of the junction box describes the circuit connection between the connector pins of the junction box and the circuit connection between the connector pins and the internal fuse and relay.

The meaning of each part of the Toyota circuit diagram is as follows: A represents the title symbol of each subsystem. B indicates the wiring color. For example, the color number of the wire in the circuit diagram is R, indicating that the color of the wire is red in the actual circuit.

Interpretation Toyota circuit wiring diagram The wiring diagram mainly shows the position of parts in the car, generally including the engine compartment, dashboard, body, electric seats and other parts. In addition, the wiring diagram also includes the wiring connector, the connection point and the hinge junction location diagram. The wiring connector is used to connect the circuit between the components and the wiring.

(4) Familiar with the function of the control. ( 5) Remember the circuit principle and iron polarity.(6) Understand the working status of the relay. ( 7) Achieve contact bypass by dissecting typical circuits.

First of all, when the EEE8 main ECU receives the low beam on signal sent by the E21 headlight changer SW assembly, the main ECU controls its terminal HRLY to output a grounding signal. Secondly, the H-LP relay and the H-LP relay work at the same time to close the often open contacts of the relay.

The characteristics of Toyota's wire labeling method are as follows: the requirements for power supply and ground wire are as follows: the electrical components in the circuit diagram are directly marked with words. Features: The terminal arrangement of the line connector and the usage of each station are directly marked in some circuit diagrams.

What is the wiring diagram of the car generator?

1. Check the output wiring of the generator and find B+, F, N, E, which are positive electrode B+ (thickest), excitation end F (thin wire), neutral end N, 3rd end (not wired in this figure), ground E (right side shell) respectively.

2. The automobile generator has three or four terminals. The thickest is the fire wire B, which is directly connected to the positive fire wire of the storage battery. The thinner one marked with F is the magnetic field connecting column, which is connected to the output of the regulator. The other one marked with E is the grounding (iron), which can be connected to the iron or battery with iron wire. The four lines marked with N are neutral points, which can generally be unconnected.

3. Depending on the car model, the wiring on the generator is also different. The most common ones are the following wires. The B connecting column is the thickest and largest connecting column on the generator. This wire is the output line of the generator and the positive pole of the battery;Other connecting columns include F, N - (some are marked as E).
